What if I do not have written evidence that my disability began before my eighteenth birthday?

(1) If there is no documentation available about your early developmental history, educational history, illnesses, or injuries, DDA may accept verbal information from your family or others who knew you prior to the age of eighteen to verify that your disability began prior to age eighteen. The information must be specific and reliable, and it cannot substitute for documentation that could be obtained with reasonable diligence.

(2) Additional evidence of your eligible condition and the resulting substantial limitations is still required.
